CLIP FOR THE ATTACHMENT OF SPRINGS.

SPEC'IFIGATION forming part of Letters Patent No. 318,797, dated May 26, 1885.

Application and February a, 1885. (N0 model.)

To all 1072,0710 it may concern.-

Be it known that I, FRANK H. PLUMMER, a citizen of the United States, and a resident of Henniker, in the county of Merrimac and State of New Hampshire, have invented certain new and useful Improvements in Clips for Attaching Elliptical and other Springs; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure 1 is a perspective view of my improved spring clip or attaching device. Fig. 2 is a vertical transverse sectional view of an ordinary elliptical spring, attached in position for operation by means of my improved clips or attaching devices; and Figs. 3 to 16, inclusive, are side elevations showing various forms of springs attached in position for operation by means of my improved clips.

This invention relates to clips or devices for attaching elliptical or other flatsprings in position for operation; and it has for its object to produce an article of this class by means of which springs may be easily adjusted and securely held in their operative position.

The invention consists in the improved construction and application of the clip or attaching device, which will be hereinafter fully de scribed, and particularly pointed out in the claims.

In the drawings hereto annexed, A designates my improved clip or attaching device, which is usually to be manufactured from a strip or plate of wrought-iron, of proper dimensions to produce a'cli p of the desired size. One end, comprising about one-third of the said plate, is bent under the central portion or body of the said plate, leaving an inter mediate space, B, into which the spring may be inserted. The other end of the plate 0 is bent upward at right angles to the center portion or body, D, and provided with openings E E, to receive screws or other means for securing the clip or plate in posit-ion. The central portionor body, D, is provided, closely adjoining the leaf 0, with a perforation, F, registering with a perforation, G, formed near the edge of the underbent portion H of the clip. These perforations are for the purpose of receiving a rivet, I, by means of which the spring may be securely retained, as will be presently more fully described.

In Figs. 2 to 16, inclusive, of the drawings I have shown my invention applied for the purpose of securing the springs to rockingchairs of that class which are known as platform-rockers, and in which the rockers are mounted upon a suitable frame and connected therewith by spring-fixtures. In all of these views, J designates one of the rockers, and K one of the top rails of the frame upon which it is mounted.

In Fig. 2 the spring Lshown is an ordinary elliptical one, the upper and lower leaves of which are seated in the spaces B of the clips A A, which latter are attached, respectively, to the rocker and to the rail K. The rivets I I are arranged adjoining the inner edges of the leaves of the spring, which is thereby held securely, and prevented from coming in frictional contact withthe inner side of the rocker.

In Figs. 3 to 16 various forms of curved and angular springs have been shown, the method of whose attachment, by means of the clips A A, will be readily understood by reference to the said figures. At the points where the rivets are arranged the edges of the springs may be provided with notches to accommodate the said rivets, which will thus serve to prevent the ends of the said springs from slipping out of the clips'or fastening devices.

From the foregoing description, taken in connection with the drawings hereto annexed, the operation and advantages of my invention will be readily understood. It is simple, easily applied, and effective in operation.

I would have it understood that I do not by any means confine the application of my invention to the forms of springs herein shown,

inasmuch as numerous other forms of springs may be successfully attached by means of my improved clip or fastener; also, that the application of the clip or fastener is not confined to rocking-chairs, as it will be found useful for attaching springs to vehicles, or, in fact, wherever springs capable of being attached by my improved fastener is to be used. I also reserve to myself the right to all such modifications in the construction of my improved clip or fastener as may be resorted to without departing from the spirit of my invention.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States- 1. A clip or fastener for attaching elliptical and other springs, consisting, essentially, of a plate or body having an undcrturned end or leaf, approximately parallel thereto, an intermediate space being left for the reception of the spring, and having its other end turned or bent upward, so as to form a leaf, which is provided with perforations, substantially as and for the purpose set forth.

2. A spring clip or attaching device comprising a body, D, having perforation F, an underturned leaf, H, having perforation G,

registering with the perforation F, and an upturned leaf, 0, having perforations E E, substantially as and for the purpose herein set forth.

3. The combination, with an elliptical or other spring, of the clip or attaching device A, constructed as herein described, and having the perforations E E and rivet-holes F G, and the rivet I, all arranged and operating substantially as and for the purpose herein set forth.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.

FRANK H. PLUMMER.
